Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
Did youger my info on my john deere lx173
All I have is what you wrote in the question.. Did you send more..
sorry for the delay.. I am multi tasking.. Busy saturday.. Today..
My computer did not DING to tell me you had arrived in chat.. Sorry..
no I want to know why my john deere lx173 won't get gas from the tank to the filter
Is there gas in the carburetor bowl?
Or you are saying it does not EVER get that far.
no. I used starting fluid and it tried to start but no fuel
I heard you, but
can you SEE the filter? Can you see gas In the filter?
If you take the gas line off of the carburetor, and hold it near the ground (pan underneath), can you drain any gas out of the tank??
but what? gas is not getting from the fuel tank to the fuel filter. I have check the line and can suck gas up to the fuek filter. Is there a fuel pump i don't know about that could be bad?
Is the tank on the LX173 made your year have the tank seat, or is the tank under the hood?
in back under the seat
Then there is a fuel pump ON the engine.. Always
it is run by negative crankcase pressure
you will find it located between the fuel filter and the carburetor
ALSO, before you do anything, check the gas tank
Where is it located? what is the part number? Is there a way I can find out if it is working?
NO, not to see if it is empty, although that would be good, but to see if there is anything inside the tank that is clogging the in tank screen filter..
Often there is Something like grass, paper, the inside of the fuel cap, peanut butter and jelley sandwiches, legos, etc, in the tank.. Us a small flash light and look
OK, I have never found the sandwich, but I have found everything else including plastic bags
I have checked the tank. It is full and I can get gas from the tank , thru the line to the fuel filter
If ou disconect the fuel filter, will the fuel flow Freely toward a can on the ground??
Also, You may check the GAS CAP to see if it is venting correclty..... Often it does not
IDo you have the model numbers, type numbers, and serial numbers of the engine?
I can try that. Is there a way to see if the fuel pump is working?
CV15S-41521 May be the correct numbers from my scribbles
that would be a 15HP Kohler engine with a verticle shaft
Is there a way to see if it is a faulty fuel pump? Is the venting done on the cap itself? could it be a vapor lock?
here is a complete parts breakdown of that engine
It could be, but if you take the gas cap off, then you can test the cap to see how long it runs
does it every run longer than 3 sec
not at this point
And, I think I asked if there was gas in the carburetor bowl, but did you give me an answer?
ops, maybe I did not ask
No gas in the carburator bowl
I may have to reboot my browser, after 12 hours, My system is on snail speed
sorry for that
what do I have to do to continue?
just what I need, no arwork for your model and type engine on the fuel system
I'll stay put
I am going to send you a complete service manual to look at to keep you busy..
You shall find it Very useful
thanks. I'm going to check the gas cap be right back
Also below is the owners manual
brb after my reboot
back .. I hope this is better
looks like it
I tried to start without the fuel cap on no luck. I tried a squirt of starting fluid it tried to start but would not keep running
briggs 808656 fuel pump..
If there is No gas in the bowl of the carburetor, it can not ever run
I know yours is a kohler engine
Any way to check it or should I just get a new one?
No real way, and I am not 100% sure I am right yet.
have you been able to spot the fuel pump??
If you find the carburetor, then the fuel line will lead to the fuel pump
I forgot to look when I was outside
then there will be a fuel line leading out of the fuel pump leading to the fuel filter
when you look, I need you to see if there are aTHREE hoses conected to the fuel pump
two are fuel lines (in and out)
I know where it is
one is a vaccume tube
either goes to the breather or the engine bloc
I will check be right back
if Your pump is made this way then YES, you just go by the pump
if the pump is mechanical, you by gaskets, and rebuild the old one
If there is nto fuel pump at all, you do a total rebuild of the carburetor
Your model and type combination is the One out of 100 that Kohler has supplied Zero photos for.. I can not tell you why.. I can see all the others. but there are a couple types
OK, maybe 110 types
but only about 5 types of fuel systems on this cv15 engine
It seems to have just an in line rubber hose and a metal out to carb
But, there is a pump?
does it look like this ? http://www.google.com/products/catalog?q=briggs+808656&rls=com.microsoft:en-us&oe=UTF-8&startIndex=&startPage=1&um=1&ie=UTF-8&tbm=shop&cid=12184725817528692936&sa=X&ei=WEk0TqnSDoiNsQLpluCFCw&ved=0CBwQ8wIwAA#
No it is rectangular ,long side facing up and down,
so it is like this http://www.google.com/search?q=12+559+02-S&tbs=shop%3A1&aq=f
OK, in any case, we have determined that you have a fuel pump
You need to get the exact model numbers off your engine and take them with you
OH, yes there is a way to test the pump on this type, I forgot to day as he interrupts himself mid sentence
Take the fuel line off of the carburetor whcih leads to the fuel pump
then turn the key as if to start
if no fuel flows out of the pump while the engine is spinning, then the pump is bad
in this case, I would replace it
if there is a good amount of fuel that flows out of the hose when you crank the engine, then the pump is good and the carb needs rebuilt
I can't tell for sure. which fuel pump it is. I will try your check and then i will wait until Monday and call John Deere parts/service. Thank you very much for your time. Accept payment
